The new VTAC Quick Detach Ultralight Vertical Grips (UVG) offer hard anodized aluminum construction with the weight of polymer (just 3.8 ounces). This is accomplished by aggressively milling away excess material to leave a functional frame of a vertical grip. It is designed to be compact but still long enough to be a functional grip.
The UVG features rattle free internal battery storage for 2x AA or 2x CR123 batteries. The batteries are retained via a clever o-ring set up that is easily user replaceable if it starts to wear out. Batteries are watertight on their own so water tight storage is not necessarily needed.
The DLOC QD systems allows the UVG to be installed and removed on your rail without tools.
